CHAPTER I

INTRODUCTION

This chapter will discuss a brief about the introduction of the project. Where, it state about the purpose of the project, objective, scope of work, problem statement and advantage acquire from the project.

1.1 Introduction of the project

(19)

2 home. Leaving the light turned on continuously, lead to energy waste. Thus this project is proposed to develop a system is to facilitate the home owner to optimize usage of electricity remotely using SMS. Thus this research is carried out to provide a mechanism through the development of a prototype to provide a service to the home owner to optimize the usage of electricity through remote control using SMS services.

1.2 Objective

The objective of this project is:

 To build a GSM control for home appliances.

 To develop a system that allows for a user to remotely control and monitor multiple home appliances using a cellular phone.

 To implement a microcontroller-based control module that receives its instructions and command from a cellular phone over the GSM network.

1.3 Scope of work

There are 4 steps to developed the project.

1.3.1 Research about the problem statement:

 Find information from books, internet and supervisor point of view.

 Study about the PIC programming.

 Study about the global system for mobile communication(GSM). 1.3.2 Design and build the hardware part:

 Simulate the GSM control circuit using the Proteus Isis software.

(20)

3 1.3.3 Design software programming:

 Design PIC programming using PIC C compiler.

 Test run and troubleshoot the program.

 Request the components for this project. 1.3.4 Test run and troubleshoot:

 Link the hardware and the software.

 Tests run the project and troubleshoot if needed

1.4 Problem statement

Below show the problem possibilities occur without the GSM control System:

 The user cannot control their home appliances when they are not at home.

 Worried about the wastage of electricity when the home appliances are not switch off.

1.5 Advantages of GSM

GSM is more stable network with robust features. GSM also have a less signal deteriorations in the buildings and able to use repeaters. Talk time is generally higher in GSM phones due to the pulse nature of transmission. The availability of Subscriber Identity Modules allows users to switch networks and handsets at will. GSM covers virtually all parts of the world so international roaming is not a problem

1.6 Peripheral Interface Controller (PIC) advantages

(21)

4

 Low Cost: Prices of Peripheral Interface Controller vary from few hundreds to few thousand. User can use the microcontroller many times.

 Testing: A Peripheral Interface Controller program can be tested and evaluated in a lab. The program can be tested, validated and corrected.

 Visual observation: When running a PIC program a visual operation can be seen on the screen. Hence, troubleshooting a circuit is really quick, easy and simple.

 Space Efficient: Today’s Peripheral Interface Controller memory is getting bigger and more complex. It is small design device which can operate as small computers.

 Reliability: The PIC controlled system often resides machines that are expected to run continuously for many years without any error and in some cases recover itself if an error occurs.

 Performance: Many of PIC based embedded system use a simple pipelined RISC processor for computation and most of them provide on-chip SRAM for data storage to improve the performance.

 Power consumption: A PIC controlled system operates with minimal power consumption without sacrificing performance. Power consumption can be reduced by independently and dynamically controlling multiple power platforms.

 Memory: Most of the PIC based systems are memory expendable and will help in easily adding more and more memory according to the usage and type of application.

1.7 Project Basic operation:

(22)

5 safety reason, but this will waste the electricity. Therefore, this application will try to solve these problems. It will let the users to control switch at home through their mobile. Users can control their home appliance by using a mobile.

The project is aimed at developing and testing the use of mobile phones to remotely control an appliance control system. The microcontroller would then control a device based on the information given to it. The proposed solution will need to be easy to use, simple, secure, robust, and be useful on most mobile phones. To achieve this testing will need to be carried out to create a useful system.
